In Chenopodium the nut remains surrounded by persistent perianth and is known as utricle. It is hard and stony in mango; fleshy and edible in banana and tomato. These fruits develop from superior or inferior syncarpous gynoecium. It dehisces in many ways. The … During development the margins of the carpels may be fused (e.g., in Annona squamosa) or they may remain separate from each other (e.g., in Artabotrys odoratissimus). The locules are separated from each other on maturity by an explosive mechanism. This type of fruit is characteristic of Cucurbitaceae family, e.g., gourd, cucumber, melon, watermelon, squash, etc., the fruit is fleshy or pulpy and many seeded. 3) Multiple Fruits. Hops, Pineapple and Jackfruit. It develops from superior, polycarpellary and apocarpous gynoecium. In simple words we can say that - Fruits of individual flowers closely packed to form a single fruit. The inflorescence axis and the flowers all become fleshy.

As adjectives the difference between composite and aggregate the cluster of flowers rather than a single flower. On the surface of the fruit, the hexagonal areas represent the flowers, and the tips of the floral bracts project out. It develops from an inferior, bicarpellary ovary. The inner walls of the endocarp give rise to numerous juicy outgrowths which makes the edible part of the fruit, e.g., orange, lemon, etc. It develops from a single carpel or from a syncarpous pistil with axile or parietal placentation, e.g., tomato, grapes, brinjal, guava, papaw, etc. An aggregate of these fruits borne by a single flower is known as an etaerio. b) Multicarpellary syncarpous gynoecium. The inflorescence axis produces a tuft of vegetative leaves, which forms a crown at the top. The stem is short and leafy and bears a terminal spicate inflorescence. The fruits generally break into many or few one-seeded portions, the mericarps. Plant scientists have grouped fruits into three main groups, simple fruits, aggregate fruits, and composite or multiple fruits. Simple fruits are those which develop from a flower having either monocarpellary or polycarpellary syncarpous pistil. Each loculus may possess one or two ovules. The examples are commonly found in Asteraceae (Compositae family, e.g., sunflower, Cosmos, Tagetes, Ageratum Sonchus, etc. The achenes are commonly developed from an apocarpous pistil, and therefore a single flower produces as many achenes as many free carpels are there, e.g., Clematis, Naravelia, Ranunculus etc. In Litchi the nut develops from a tricarpellary, syncarpous, superior and trilocular ovary with more than one ovules. Aggregate fruit – Aggregate is a group of fruitlets formed from a flower having two or more free ovaries .
